Guidance for SAP BASIS Self Study

Hi All,

This is Arun and i am grateful to be part of the community.I am working currently as a SAP deployment consultant. As my career is concerned, i am into only a few parts of BASIS and did not have instructor led training of overall BASIS module. I want to grow my knowledge and learn as much as i can in BASIS. The point here is, i want to learn SAP BASIS by self-studying. Please suggest me the way and tools to do it. Thanks in advance.
